The 2007 Microsoft Office system is a major release that offers
many improvements and new features in response to customer needs.
Changes such as the new file format and new Setup architecture
require careful planning and preparation before your upgrade. Your
migration planning includes evaluating the files in your
environment, identifying potential conversion issues, and reviewing
migration considerations for each program within 2007 Office
system.

The process for migrating from Microsoft Office 2000 to the
2007 Office system is similar to the process for migrating from
Microsoft Office 2003 to the 2007 Office system. It is
important to review the system requirements for the 2007 Office
system. You should also review the differences between
Office 2000 and Office 2003, in addition to the
differences between Office 2003 and the 2007 Office
system.

One of the biggest changes in the 2007 Office system is the new
file formats. You can use the Office Migration Planning Manager
(OMPM) to assist with migration efforts. OMPM helps you to examine
the files in your environment and to decide whether to archive
them, convert them in bulk with the Office File Converter that is
available in OMPM, or convert them manually. OMPM is designed for
migrations between Office 2003 and the 2007 Office system. You
can also use the tool to assist in Office 2000 migrations, as
long as you have at least one computer configured to meet OMPM
system requirements.

Note:

OMPM detects migration issues for files that
are developed with Office 2003 applications, and might not
detect all migration issues between Office 2000 to
Office 2003. It is important to review migration issues from
Office 2000 to Office 2003 to determine whether any of
these might affect the files in your organization.

Your migration plan from Office 2000 to the 2007 Office
system should include the following steps:

Review differences between the 2007 Office system and Office
2003. See Differences in the 2007
Office system. Many of these issues are detected by the OMPM
Office File Scanner. Other issues might require a difference in
user behavior, or might require changes in custom solutions.
